WAGON LOADER.

Application viiledlecember 15, 1919.` Serial No. 344,938.

To all/whom t may concern:

Be it known that I, LESLIE. A. RUSSELL,

a citizen of the United States of America,

and a resident of Chicago, Illinois have invented a certain new and`useful 2Iniprovement iii Wagon Loaders, of which the following i's aspecification.

This invention relates to wagon loaders of the kind in which means areprovided for feeding the materials from a heapi or mass on thestreet-into a wagon or truc or other receptacle by means of an elevatorwhichis constructed and arranged to carry the materials upward to apoint where they l5 are then discharged downwardly into the box orreceptacle of the wagon or truck,

rdinarily, in wagon loaders of the machine which constitutes the loaderis provided with its own source of motive power to operate saidelevator, and, ifdesired, to supply the power for movingthe rmachinealong thestreet, so that the latter is driven by its own power.

Generally stated,'the object of the invention is to provide an improvedconstruction and varrangement whereby the engine or other motive ower ofthe motor driven truck or dumplng vehicle which receives the materialsfrom the upper end of the elevator is also available for the operationof the latter, so that the wagon loader 1s not required to have anengine or motor for the operation thereof, the power for this purposebeing supplied from the engine or lmotor of the motor truck dumpingvehicle 4into which the materials are loaded from lthe upper end of theelevator. i

It is also an object to provide a novel and improved arrangement wherebythe wagon loader is adapted to be transported from place to place as atrailer behind the motor truck dumpingl vehicle, so that the motivepower of the latter is available for this puras well as for operatingthe elevator while the wagon loader is standing still.

Itis also an object to provide certain details and features ofconstruction and combinations tending to'increase the general efficiencyand the desirability 'of a wagon loader of this particular character.

To these and otheruseful ends, the invention consists in mattershereinafter set forth and claimed, and shown in the accompanyingdrawings, in which- Fig. l is aside elevation of a motor truck dumpingvehicle and a, wagon loader embodying the principles of the invention,

showing the frame of the wagon loader-in longitudinal Section.

Fig. 2 is a plan of the wagon loader frame. Figs. 3, 4, 5 and 6 arefragmentary detail sectional views, showing different portions of thewagon loader mechanism. As thus illustrated, the motor truck dumpingvehicle has a chassis 1 of any suitable character and a box orreceptacle 2 'of-'the usual or any suitable form, ada ted to opcrate inthe ordinary or any suita le manner to dump the load. The engine islocated 1n the hood 3 in the usual and well known manner, and issuitably connected with the i transmission in the gear casing 4 to drivethe jack-shaft 5, which latter is suitably connected tovoperate the rearwheels 6 of the vehicle. Said gearing ordinarily has a projecting shaft7, and in accordance with the invention a pinion 8 is mounted on thisshaft and a hanger 9 is supported on the end of said shaft, this pinionand hanger being simply slipped onto, the'projecting end of said shaft,so that in any machine in which the gearing is of such character that ithas this projecting shaft no alterations are necessary. One end of thelongitudinal shaft 10 is supported in this hanger 9, and is providedwith a gear 11 which engages said pinion, Said shaft being suitablysupported in bearings on the body frame 12 of the wagon loader. Saidshaft has the universal joint 13' adjacent the gear 11, and

another universal joint 14 'near the front end v of the frame 12, withpreferably a, telescoping connection with the joint 14 at a pointbetween the two universal joints, for a purpose which will hereinaftermorefully appear. forward end, to connect it with the front end portionof this frame, which end portion 'is detachably clamped upon the squaredrear axle 16 of the motor vehicle, as by a clamp 17 pivoted at 18 toswing over and rest upon said axle, this clamp being then securedy inplace to the bracket 19 by means of the latch or catch 20, which lattermay be of any The frame 12 has a pivot 15 at its nos 'suitable orordinary character. Thus, when the front portion21 of the wagon loaderybody frame is clamped upon the rear axle of the motor vehicle, the rearportion of street. `Said wagon loader is also provided i ,with frontwheels 23 to support the machine when not connected with said motorvehicle. However, when the wagon. loader is hooked up as a trailer tothe rear ehd of the motor vehicle, the wheels 23 are then -raised yfromthe street by means of the hand wheels 24 which operate the screws 25,the latter being connected with the bearings 26 which slide up and downin the guides 27 on the `body` frame of the Wagon loader, said screws 25'being threaded in the bearings 28 which are supported by brackets 29 onthe body frame of the wagon loader, whereby rotation of these handWheels 24 will raise an'd lower .the axle 30 upon which are mounted saidfront wheels of the wagon loader. Thus,

when the wagon loader is connected to the motor truck, the wheels 23 canthen be raised from the street, so that the Wheels 22 and the axle 16will support the entire weight of the wagon loader.

Saidpwagon loader has a ladder frame 31 pivoted at 32 on the uprightframe 33, which latter is suitably secured on said body frame.

Said elevator has an endless chain of buckets 34 for carrying thematerials upward, being mounted on the upper and lower sprockets orrotary members 35 and 36, and said buckets being adapted to dischargeinto the spout 37 at the upper end of said elevator whereby thematerials are then discharged into the box or receptacle 2 from themotor truck dumping vehicle. The lower end of the elevator is preferablyprovided with a feeding device 38, of an suitable, known or approvedcharacter, to acilitate the feeding of the materials from the mass orhea on the street into the buckets of the elevator. To tilt the elevatorabout its axis 32, a rack 39 is pivoted on the elevator frame at 40,andv adapted to engage a pinion 41 which is operated by the worn gearing42, the latter having a hand wheel 43 for the operation thereof, andsaid pinion and worm gearing being suitably mounted on the frame 33 ofthe wagon lo er. v

To drive the elevator, the upper end thereof is connected by a sprocketchain 44 with the sprocket Wheel 45 on the horizontal axis 32 aboutwhich the elevator tilts, when it is desired to raise the lower end fromthe street. Another sprocketchain 46 connects this shaft or axis 32 witha, shaft 47 on the frame, and bevel gearing 48 connectsv the shaft 47with the previously mentioned shaft 10, so that power is communicatedfrom the engine` of the motor loader having means for @leasesvehicle-to' operate the l elevator. yad hand` From the foregoing it willber seenthat` no power plan is necessary :on the wagon loaderv itself,inasmuch as the operation thereof is `accomplished. by means of power aderived from the engine of the motor vehicle. Also,"as. shown, the wagonloader is adapted to' be transported asa trailer behind the vehicle,when lthe wheels 23l are raised from the ground, so that the powerof'the motor vehicle is suiicient for all requirements.
